You can use them for personal or commercial projects, and I ask for no money. I would, however, love to hear from you. If you use my fonts for something please e-mail me letting me know how you used it. Send me a copy if you can or let me know where I can find your work. You are under no obligation to do this, I just like to see how my fonts get used. A license.txt file should have been included with this font, explaining the license under which it is made available. You can also read it at: http://www.squaregear.net/fonts/license.shtml About the font: Can you believe there are people who would charge you for a barcode font like this? It took very little time to make this so I thought I'd donate it to the world. It is suitable for scanning even at fairly small point sizes. I have tested printed copies of this font with a couple different scanners and it worked perfectly. This is 3 of 9 (sometimes called "code 39"), a widely used barcode standard that includes capital letters, numbers, and several symbols. This is not the barcode for UPC's (universal price codes) found on products at the store. However, most kinds of barcode scanners will recognize 3 of 9 just fine. To create a valid 3 of 9 barcode you have to begin and end it with a special character. Scanners look for this character to know where to start and stop reading the barcode. It is represented in this font with the '*' character. So, to create a barcode for the text "ABC123" you have to type out "*ABC123*". Note that barcode readers will not include the *'s in the text they return. They will just give you the "ABC123". Two versions of 3 of 9 are included. The font called "Free 3 of 9" is the basic 3 of 9 standard. It includes letters and these symbols: $ % + - . and /. The font called "Free 3 of 9 Extended"
